Appl. No.:

08/966381

Inventors:

Sang W. Kim - Lawndale CA

Assignee:

International Classification:

G06F 900

US Classification:

709104, 709107

Abstract:

Temporary states are used transitionally in run-time situations and are unknown to the object database. A temporary state is created if, when an object is performing a requested event, interim work needs to be performed before the object reaches a permanent destination state. Use of a temporary state is transparent to the caller of the requested event. Within a single flow of control, an unlimited number of nested locks may be acquired. A request to unlock an object will only truly unlock the object if the unlock requester is at the highest level of locking. For recursive or embedded functions, no knowledge of the previous locking condition is necessary. Attribute-based locking provides a mechanism for allowing only certain members of the system to lock an object for writing while the object is in a predetermined state. However, any thread may obtain a read lock on an object in order to examine its attributes. This may be expanded to state that the system may restrict locking of an object or entity based upon any attribute in the database or upon any combination or logical expression of these attributes.

Abstract:

A parking guidance and management system. The system provides graphical information regarding the relative availability of parking spaces within a parking garage or other large facility. The system relies on a pair of sensors in each space which combine to provide highly reliable information regarding whether spaces in the facility are occupied or not. The information is gathered by a series of aisle controllers, which communicate with a central computer. The information is displayed at strategically located displays along the way to available spaces. The displays contain advertising messages adjacent to the information about space availability. The information obtained from the sensors at each parking space may be used to provide information to the manager of the facility regarding space utilization. Information regarding the occupancy status of each space may also be used as a check on receipts of parking fees and to identify abandoned vehicles.

Appl. No.:

11/467433

Inventors:

Sang Hoon Kim - Grayslake IL, US

Assignee:

Micrel, Inc. - San Jose CA

International Classification:

G05F 1/00

US Classification:

323283, 323222

Abstract:

A synchronous switching regulator controller incorporates a switch detection circuit to determine the presence or absence of a power switch at the output of a switch driver so that the switch driver can be disabled when it is left unused. In one embodiment, the synchronous controller includes a switch detection circuit receiving a power cycle signal and the PWM ramp clock signal and measuring a voltage at an output node of the switch driver. The switch detection circuit provides a driver enable signal in response to the assertion of the power cycle signal. The driver enable signal has a first logical state when the voltage at the output node of the switch driver is greater than a reference voltage and a second logical state when the voltage at the output node is less than a reference voltage. The switch driver can be disabled based on the driver enable signal.

International Classification:

A61C 5/09
A61C 5/10

US Classification:

4332221, 433223

Abstract:

A coping material for a prosthetic crown is provided. The coping material according to current application is comprised of two portions which are mechanically bonded each other. The first portion is the main coping portion that is located beneath of the enamel layer of a crown. The first portion is made from, including but not limited to, common metal and/or portion fused gold (PFG). The second is the portion which makes contact with gum tissue. That portion surrounds the brim of the bottom of the coping for 360 degrees. The gum contacting portion is comprised of bio-gold that is mechanically bonded to the main coping portion. Centrifuging of molten bio-gold technology is applied for mechanical bonding of the two portions. Electronic forming technology is also applied for mechanical bonding.
